Daly Travel® | 🚀 Which US Airline Has the Oldest Fleet? ✈️
If you’ve ever wondered which major US airline operates the oldest planes, the answer is United Airlines. With a median fleet age of 19.4 years, nearly half of United’s aircraft are 20 years or older, including Boeing 767s that have been flying for over 33 years!
Here’s a quick snapshot of median fleet ages across major US airlines:
• United Airlines: 19.4 years
• Delta Air Lines: 17.2 years
• American Airlines: 11.1 years
• Southwest Airlines: 11.5 years
• Spirit Airlines: 6 years

Interestingly, many low-cost carriers operate much newer fleets, reflecting their focus on fuel efficiency and passenger comfort.
Fleet age impacts everything from operational costs to passenger experience, making it a key factor in airline strategy and competitiveness.
